The images are this page are from the New Player Welcome puzzle, and were posted back in 2011.

The New Player Welcome puzzle has since been retired in favor of six beginner puzzles, which run in constant rotation.

While the New Player Welcome puzzle is gone, this gallery is still a good guide on using some of the tools available in Foldit. It uses "hand folding", relying on bands, Shake, Wiggle, Rebuild, and Tweak to shape the protein. It uses the original interface, since the selection interface was not available at the time.
